As far as I know Vegas doesn't add anything.
I think we need a few more details.
In general though the if you are viewing video on a PC monitor you
will see interlacing artifacts. This is unavoidable as you are viewing the interlaced video on a progressive scan device.
Of course it could also be any one of another other possible things.

Okay here's a sample.

This is part of a 3D animation. On the left is the original frame. Middle is interlacing set to lower field, and show the artifacts I beleive you were talking about. On the final frame I set interlacing to Progressive Scan. As you can see there appears to be some kind of after image. Is this also an interlacing artifact?

Try playing around with the Deinterlacing options in the Project Settings window. When you create a progressive frame Vegas has to deinterlace the source video, and the way this is done (frame blending or interpolation) will affect the result.

In general, if your source is interlaced and your final output is TV, you will get the best results by staying in interlaced format all the way. If you do have to deinterlace, the ghosting you are seeing is quite typical (actually it looks pretty mild to me compared with some I have seen).

Would this kind of computer generated file be interlaced though? The source file is an mov quicktime file. Those aren't interlaced are they?

Quiicktimes can be interlaced or non-interlaced, just depends on what you've done in rendering the file.
Right click it, you'll see if it's interlaced or not in the properties.
Plus, whether it's interlaced or not, if you've got Vegas' property settings at NTSC or PAL standard, it's gonna get interlaced.
